Field Validation Function - How can I run on a Deal CREATE as well as an UPDATE?

Field Validation Function - How can I run on a Deal CREATE as well as an UPDATE?

greetings.. I am running some address validation logic using an onChange() validation on the field.
When it runs during an edit/update Zoho CRM sends the Deal ID as part of the payload, so everything works.

When it runs during a new/create operation, there is not yet a record created.. so I am unable to parse the data field and populate the fields at this time.

How can I best accomplish this?

Code provided below for your reference:
  2. //
  3. crm_record = crmAPIRequest.toMap().get("record");
  4. if(crm_record.containKey("id"))
  5. {
  6. existing_record = true;
  7. job_id = crm_record.get("id").toLong();
  8. }
  9. else
  10. {
  11. existing_record = false;
  12. }
  13. //
  14. url_encoded_address = zoho.encryption.urlEncode(crm_record.get("full_home_address"));
  15. //
  16. // Retrieve the API key for LocationIQ out of the "CRM Variables"
  17. api_key = zoho.crm.getOrgVariable("locationiq_api_token");
  18. //
  19. // Run the validation using LocationIQ
  20. location_response = invokeurl
  21. [
  22. url :"https://us1.locationiq.com/v1/search?key=" + api_key + "&q=" + url_encoded_address + "&format=json&addressdetails=1&limit=1&countrycodes=us&normalizeaddress=1"
  23. type :GET
  24. detailed:true
  25. ];
  26. //
  27. class = location_response.get("responseText").get(0).get("class");
  28. place = location_response.get("responseText").get(0).get("place");
  29. //
  30. return_value = Map();
  31. //
  32. if(isNull(class))
  33. {
  34. return_value.put('status','error');
  35. return_value.put('message','Provided address does not validate');
  36. }
  37. else
  38. {
  39. if(existing_record)
  40. {
  41. address_components = location_response.get("responseText").get(0).get("address");
  42. //
  43. new_full_address = address_components.get("house_number") + " " + address_components.get("road") + ", " + address_components.get("city") + ", " + address_components.get("state") + " " + address_components.get("postcode");
  44. //
  45. updated_address_fields = Map();
  46. updated_address_fields.put("full_home_address",new_full_address);
  47. updated_address_fields.put("Description",new_full_address);
  48. updated_address_fields.put("address_house_number",address_components.get("house_number"));
  49. updated_address_fields.put("address_street",address_components.get("road"));
  50. updated_address_fields.put("address_city",address_components.get("city"));
  51. updated_address_fields.put("address_state",address_components.get("state"));
  52. updated_address_fields.put("address_zip",address_components.get("postcode"));
  53. updated_address_fields.put("Address_Validated",1);
  54. //
  55. update = zoho.crm.updateRecord("Deals",job_id,updated_address_fields);
  56. //
  57. }
  58. return_value.put('status','success');
  59. }
  60. //
  61. return return_value;

Thank you for any assistance you can provide.
